I did a search and found a ton of posts that did not answer this question. It seems very simple, so maybe I am just having a brain fart.
When it says: The entire brood may exchange is scything talons for: X at Y points a model, etc. does that mean that they all must have the same weapon option selected and which will add Y points per model in the brood OR that all of them may exchange, and can exchange for any of the listed options?
Thank you for clearing the air...
